Ava desperately wants a pet for her eleventh birthday—but gets way more than she bargained for when she adopts T-A-C-O-C-A-T.

When Ava Wren hears about an injured yellow tabby with mismatched ears, she becomes obsessed and wants to rescue him. She even picks out a perfect palindromic name: T-A-C-O-C-A-T. But when Taco joins the family, he doesn't snuggle or purr—all he does is hide. Worse, Ava's best friend starts hanging out with Zara, a new girl in fifth grade. Ava feels alone and writes an acclaimed story, "The Cat Who Wouldn't Purr." What begins as exciting news turns into a disaster. How can Ava make things right? And what about sweet, scared little Taco?

The New York Times called Ava and Pip "a love letter to language." With this second diary, Girls' Life advice columnist Carol Weston hits another home run.
